碩士 === 國立交通大學 === 電信工程研究所 === 106 === The problem of communicating over a multiple-input single-output (MISO) broadcast channel using zero-forcing dirty paper coding (ZF-DPC) is considered. Assuming a total power constraint, several commonly used design-objectives for power allocation, aiming for either a large sum-rate, a better fairness or both, are first reviewed. Besides the existing quantitative measure of fairness, a new fairness measure based on L1 norm is provided. A novel design methodology, termed tri-stage approach, is then proposed and is shown to provide a better tradeoff between achieved sum-rate and fairness than the existing designs from simulations.
